The Perfect Score
The Perfect Score Custom-fit wedges and putters have a positive impact on a golfer’s game. By Jeff Sheets Drive for show and putt for dough. Most everyone who has heard this mantra recognizes its merits, yet few golfers take the time to get their most important scoring club custom-fit to him- or herself. The performance of one’s scoring clubs, or putters and wedges, can make all the difference between a spectacular round of golf and one that is mediocre. As with a set of irons, there is a process for fitting scoring clubs. In fact, if you know how to fit a set of irons, you’ll find that fitting scoring clubs is no more difficult. The greatest difference between swinging a wood and iron versus a shortgame club is the length of the swing. With a wood or iron, the golfer takes the club to a parallel position at the top of the swing. This is not the case with a wedge or a putter. Partial swings dictate the use of the scoring clubs and this is where the differences influence the fit. This month, we take a look at the primary focal points on custom-fitting wedges and putters to a golfer. 14 ■ April/May 2007 Golfsmith Clubmaker 07CM7_JulyCM_feat1_op1.indd 14 6/12/07 5:29:51 PM Wedges T ypically, a wedge fitting occurs in conjunction with an iron or full-set fitting, but this is not always the case. Many of the same protocols you would take in an iron or wood fitting also apply to the wedges. Determine the golfer’s clubhead speed using a driver or 5-iron to arrive at the correct shaft recommended swing speed range (RSSR). Measuring for club length and grip size is no different with the wedges, either. And of course there is the lie angle measurement. This is extremely important because there is so much loft on the wedges. These are intended to be the scoring clubs, so a precision lie specification must be perfectly set! Conducting a dynamic lie angle fitting is necessary with wedges, even if it has already been done with irons. With a more abbreviated swing and narrower — and often open — stance with the wedges, a lie angle that is unique from the irons is possible. Using impact tape on the sole of the club and having the golfer hit balls from an impact board will indicate the need to adjust the wedge’s lie angle. Determining the set configuration of the wedges is in order. With 14 clubs as the limit, does the golfer have room in the set to accommodate four wedges? Perhaps only three? I am a big advocate of replacing bad utensils with good ones. If the golfer has a long iron that fails to perform consistently, replacing it with another wedge loft could pay a higher dividend: Better scores. The important approach in selecting wedge lofts is to maintain consistent loft intervals between clubs, for tight, predictable distances in yardage. Most mid- and short-irons Keeping this consistency between wedges is preferable. As the set flows from the pitching wedge to approach (or gap) wedge, sand wedge and onto the lob wedge, a consistent loft interval provides the golfer the means to control scoring club distances. In some cases, a golfer may only be able to accommodate three wedges in the set. In this situation, the wedge types must be carefully considered based on the golfer’s short game. For example, a set configuration of a pitching wedge, sand wedge and lob wedge would dictate five to six degrees of loft between each club based on the weakest loft (lob wedge) of the set. But a golfer selecting a pitching wedge, approach wedge and sand wedge as the three-club set can usually keep an increment of four degrees of loft between each club since a lob wedge is forfeited. Many golfers who want a lob wedge choose a 60-degree model by default, simply because it has been the standard loft for lob wedges since they were first introduced in the late 1980s. Unfortunately, many recreational golfers display an inconsistency in distance control with 60-degree lob wedges. While one shot may travel 45 yards, the following can unexpectedly fly 60 due to the great amount of loft on the lob wedge and results from variable impact locations vertically along its face. Snake Eyes 655TM Wedge Head (No. SE2666) In fitting recreational golfers to lob wedges, the best remedy for this inconsistency is to bump the loft stronger, to 58 degrees. This helps tighten the gap between each club in a three-wedge set but more importantly provides greater distance control, especially to those who do not routinely practice with their lob wedges. Another popular trend in wedge fitting is to use the lob wedge as the greenside bunker club. Historically the sand wedge, typically with 54 to 56 degrees of loft, has played this role, but most tour players now use their lob wedges for this function. The higher loft helps get the ball up over a bunker’s lip easier and allows for it to land softer than with a stronger loft. The bounce angle of the sole also plays a vital part in the fitting process. The soles of wedges incorporate a trailing edge that is angled lower than the leading edge. In the sand or deep rough, the sole acts like a water ski does on the surface of a lake. It keeps the clubhead from burying itself, as long as the golfer follows through with the swing. Selecting the correct bounce angle for the wedges becomes part of the custom fit. In regard to bounce, there are two areas to focus on; the sand is the first. A golfer who needs help keeping the clubhead from digging in the sand requires a wedge with a greater degree of bounce on its sole. Minimally, 12 degrees should be considered, but 14 to 16 degrees could prove to be more helpful, because the greater the amount of bounce, the better the clubhead will slide through the sand without digging deeper. A highly skilled bunker player can get by with as little as eight to 10 degrees of bounce. The skilled ball striker can equally benefit from greater bounce in the bunker, but will find that a high-bounce sole can be restrictive off the fairway, on hardpan or for hitting finesse shots around the green. There is give and take with regard to selecting optimal bounce. clubmaking.golfsmith.com ■ 07CM7_JulyCM_feat1_op1.indd 15 15 6/13/07 3:44:24 PM Wedges Light, powdery sand is a condition where even a good bunker player may require a higher bounce angle on the sand wedge. The opposite is true for a very hard-packed bunker. Approach this shot as if it were a hardpan situation, where little bounce is necessary. If the golfer often plays at a course with either of these conditions, having wedges with the appropriate amount of bounce can be a big asset. The condition outside the bunker becomes another consideration in choosing a wedge’s bounce. A high-bounce wedge that works well in soft sand may be a detriment outside of the bunker. For many golfers, a sand wedge with 10 to 12 degrees of bounce appears to be the most versatile in and out of sand. When fitting the golfer for wedges, take note of the player’s angle of attack. A steeper angle of attack will require more bounce on all of the wedge’s soles. The higher bounce angle helps restrict the depth of a divot, which may become too deep and long without enough bounce in the sole. For a golfer with a shallow angle of attack, very little to no bounce is necessary. These golfers are easy to spot: After hitting a full bucket of balls, there are no divots and no turf is missing from the practice spot. Sweepers, or pickers, of the ball would actually find that too much bounce impedes their swings, so selecting wedges with less bounce throughout the set would be preferred. Further attention should be paid to the wedge soles. Sole design is very important. For example, the width of the sole plays an important role in conjunction with the bounce angle: The wider the sole, the more dynamic the reaction of the bounce angle, whether in the bunker or off the grass. Many soles have design features, such as relief in the heel area, that enable the wedge to lay open for execution of flop shots. A pre-worn sole has material relief running from heel-to-toe to shift the bounce angle to the trailing edge, making shots off tight lies easier to execute. Basically, the design of the sole dictates the versatility of the wedge. Whether targeted for the bunker, rough or fairways, a variety of sole angles are conducive to many different conditions and shots. In fact, this is one area where custom grinding can prove to be a valuable skill set for the Snake Eyes GBU Forged Wedge Head (No. SE2680) fitter. Creating a sole shape that meets the specific needs of the golfer, while hitting the bounce angle and width, can sometimes only be done through custom grinding — just ask the touring pros. The focus has been on the head so far, but we must also fit the proper wedge shafts into the golfer’s set. A full shot made with a sand or lob wedge equates to no more than a three-quarter swing with an iron or wood, and much less amplitude is placed into the shaft. (It does not flex as much at the start of the down-swing.) This leads to less feedback from the shaft, so there are considerations that should be made in regard to promoting feel. This is even more important when it comes to chips and pitch shots. I recommend a shaft that is at least equivalent in weight to, if not heavier than, the set’s iron shafts. Heavier weight promotes greater feel throughout the swing, and this is most important on partial swings. A softer shaft flex also promotes greater feel on a partial swing. Softening the wedge shafts can be achieved by soft-stepping the same shafts used in the irons. For example, if the trimming instructions call for a four-inch tip cut, tipping the wedge shaft two to three inches instead will lead to a softer feel. Using a softer flex shaft (i.e., the golfer plays a stiff in the irons, so a regular flex is used in the wedges) is yet another way to promote more club feel. Finally, ensuring that the swingweight of the wedges is heavier than the irons will also promote more feel on partial swings. It is not uncommon to find pitching and approach wedges one or two swingweights heavier than the irons, and sand wedges at least three swingweights heavier than the rest of the set. In combination, a heavier shaft, softer flex and higher swingweight in each wedge provide greater feedback to the golfer’s hands around the green. The last remaining spec to complete the wedge fitting is the club length. Many original equipment manufacturers (OEMs) lop off all of their wedges at the same length. This makes mass production easier but does nothing to promote lower scores. Too many golfers focus on how far they are capable of hitting their wedges, but scoring has nothing to do with distance and everything to do with control. As the loft weakens in the woods and irons, so do the shaft lengths. There should be no deviation from this system when it comes to the wedges. Shorter clubs are easier to control, and scoring is all about control. The most common approach to addressing wedge lengths is to reduce club length increments to one quarter inch, beginning with the pitching wedge. Whereas halfinch length increments are common with irons, most wedge head weights are manufactured to be assembled at quarter-inch increments. Fitting the wedges with half-inch increments between each loft could be considered as long as the heavier swingweights can be maintained through hosel weight ports, lead tape or custom grinding. With a properly fit set of wedges, the golfer has the right tools for the job. 16 n July 2007 Golfsmith Clubmaker 07CM7_JulyCM_feat1_op1.indd 16 6/18/07 11:15:01 AM Putters N ow that the golfer has been fit to the wedges, we need to ensure the flatstick has been optimized to the putting stroke. The putter is a completely different implement from the rest of the clubs in the set: It is (typically) the shortest club with the least amount of loft, requiring a stroke that is not at all similar to the golf swing. There’s one other thing about the putter: Many putter owners have a love/hate relationship with it. While a golfer can get into a good putting groove and intuitively make everything in sight, a cold spell never seems to be too far down the road. Having a putter that has been dynamically fit is a good way to minimize those dreaded cool-down periods. As with fitting any other club, there are a handful of specifications to address to guarantee a good marriage between golfer and putter. When starting a putter fitting session, be sure that you have access to a putting green, whether it is natural grass or inside. Otherwise, the fitting should occur on a carpet that is smooth enough to roll putts at least 20 feet. The length of the putter is one of the most important variables in which to fit the golfer. For decades, the standard putter length sold by OEMs was 35 inches. The industry is beginning to see a decrease in the lengths offered, and with good reason. At Golfsmith, we have been fitting golfers to their putters for years, and few end up with a club that is 35 inches in length – in fact, most of the golfers we have fit end up with lengths in the 32.5- to 34-inch range. My preferred way to determine the proper putter length is to begin with a fitting putter that has an uncut shaft and no grip. The putter itself will be approximately 37 to 40 inches long, depending on the head style and Snake Eyes Z-9 Model 2 Putter Head (No. SE4791) the shaft used. I recommend making two fitting putters – one with a conventional style head (i.e., a heel-toe model similar to the ever-popular PING Anser), and the other with an alignment (mallet) design. Most golfers will usually be fit to one of these two categories, depending on the latest design trends. Have the golfer set up to the fitting putter using their normal setup. For most golfers, this is a shoulder-width stance, eyes over the ball and arms hanging freely from the shoulders. Because there is no putter grip, the golfer can set up to the putter without any influence on their hand placement. (Golfers typically place their hands lower on the shaft when there is no grip on the putter.) Now have the golfer roll a series of practice putts, adjusting the hands for comfort and control. These two factors are very important: If the golfer is not comfortable with the location of his or her hands, there is less ability to gain control of the stroke. Once you have identified the preferred hand position, mark the shaft one inch above the crook of the golfer’s upper wrist. This will be where the shaft is cut. Golfsmith also markets a Putter Fitting System (No. 240789) that has a telescoping shaft. This accomplishes the same objective by placing the hands in a comfortable and controlled position. Once the golfer’s putter length is determined, the lie angle is ready to be set. As opposed to using impact tape on the sole like an iron, observe the sole orientation to the ground as the golfer strokes at the ball. Lie angles can be easily adjusted using a bench vise to secure the head as the hosel or shaft is bent to the correct spec. A precise lie angle fit for a putter is less critical than the wedge lie due to the lack of loft. In fact, many golfers fit into an upright lie purely as a setup visual. I suggest setting the lie angle so the sole is flush to the putting surface, but definitely give in to the preferences of the golfer in this situation. Once again, the Putter Fitting System is available to set the appropriate lie angle as well as club length. Golfsmith Adjustable Putter Fitting Tool (No. 240789) clubmaking.golfsmith.com n 17 07CM7_JulyCM_feat1_op1.indd 17 6/13/07 3:46:20 PM Putters Setting the putter to the most efficient loft is an enigma to most fitters. The objective with the putt is to get the ball rolling with over-spin as quickly as possible, but loft on the putter face imparts backspin as the ball comes off of the face. As the backspin transitions to over-spin, the ball ends up skidding. When setting the putter to the best loft for the golfer, the goal is to minimize skidding. Instead of using a 50,000 frames-per-second camera to observe the ball skid, a much simpler tool can monitor the skid — your ears. Listening to the skid provides insight to the efficiency of the roll. For starters, the golfer should be rolling putts 20 or more feet in length. This will ensure enough audible feedback in listening to the ball skid. A putter with an adjustable loft feature such as the Putter Fitting System can alter the loft as putts are rolled. What I have used in the past are three identically built putters with lofts of one, four and seven degrees. As the golfer is rolling putts, listen to the putter that provides the shortest sounding skid. In a scenario where a golfer forward-presses, the putter is de-lofted and you will hear excessive skid with the one- and four-degree lofted putters. However, with the seven-degree loft, there will be less skidding. This feedback directs the fitter into setting a higher loft spec for the golfer. In a test where the one- and four-degree putters sound similar, but the seven-degree model provides a longer skid, the golfer’s most efficient loft may be two or three degrees. Using the assortment of lofted putters to audibly identify the least amount of skid helps identify the most efficient loft, without the need for high-speed cameras or software. The next fitting specification to focus on is weight – but not swingweight. Swingweight plays a more pertinent role in woods and irons, where the club is being swung around the golfer’s body. With a putting stroke, the shaft remains primarily in a vertical orientation to the ground; it is not swung around the golfer’s spine. A need for static weight is important in a putter. Do not be distracted with swingweight specs. True Temper T2C Putter Shaft (No. T2C) Python Pure Balance 5 Putter Head (No. SE4850) During the putting stroke, it is important to use the large muscle groups of the arms and shoulders to control the club. A heavier putter will promote the use of the larger muscles, whereas if the putter is too light, the wrists and elbows have the ability to take control of the club. This is not desired. Promoting the larger muscle groups keeps the wrists and elbows quiet while maintaining better control of speed and accuracy. Ways to increase the static weight of a putter include using heavier heads, heavier shafts and heavier grips. Heads can be made heavier if adjustable weights are available for their design, and heavier heads can also be selected for the putter’s assembly. For example, heads intended for mid- and over-length putters are typically much heavier than those targeted for standard-length models. Using a newer putter model is another way to increase head weight. The standard putter head weight has increased over the past decade. Ten years ago, putter heads commonly weighed 325 grams, but today, many weigh in excess of 355 grams. Older head models may have deficiencies in both forgiveness and weight. Golfsmith codeveloped a 200-gram putter shaft, the TC2, with True Temper. It doubles the weight of the typical putter shaft, so it can quickly add weight into a completed putter without altering its balance point. Butt weights can be incorporated into the shaft to bring its static weight, up or lead tape can be wrapped under the grip prior to its installation. Putter grips themselves can range from as little as 55 grams to more than 150 grams. Do not be afraid of swapping out a light putter grip for a heavier one. While the swingweight may drop, the static weight of the club rises. The reduction in swingweight should not prevent you from using the heavier grip. 18 n July 2007 Golfsmith Clubmaker 07CM7_JulyCM_feat1_op1.indd 18 6/18/07 11:17:17 AM 72˚ Lie Face Balancing: The face axis protrudes to the center of the face. Adjustable weight putter grips such as the Tour Lock system (No. 57417) are a great way to fine-tune the static weight of a putter. With the grip installed, the interchangeable weights can be inserted and removed from the butt of the club until the golfer experiences the desired feel. Whether using a weight-adjustable grip like the Tour Lock system or a traditionally styled grip, a wide variety of putter grips is available to suit the preferences of the golfer. Whatever shape the golfer prefers — whether it is pistol, paddle, wrapped, split, etc. — recommend the largestdiameter grip the golfer will accept. The larger the grip, the quieter the golfer’s hands during the stroke. While keeping the hands quiet, the larger grip also promotes the use of the larger muscles throughout the stroke for more consistency and better control. By now, I have addressed all of the important specifications of putter fitting, except for one: Face balancing. A face-balanced putter is a model where the face points skyward when the shaft is suspended in a horizontal position. The tendency of this design is to remain square to the target line during the takeaway and follow through. This is a great feature for the golfer who keeps the putter on the target line throughout the putt. It is more stable on an off-center impact and helps to remain square throughout the entire stroke. However, it is not a good feature for a golfer who fans the putter face open and closed or takes the putter away on an inside track in relation to the target line. Face balancing in these situations works against the natural motion of the stroke. Observe the golfer you are fitting during the length and loft evaluation stages of the process. Note the take-away and follow through of their stroke. If they keep the head on line with the path, they are a candidate for a face-balanced model. However, observing any other stoke tendencies may eliminate the recommendation of a face-balanced design. You are now armed with the knowledge to perform a short game equipment fitting. Knowledge is power, and you have the power to improve other golfers’ games. That feels as good as knocking the pin from off the green on successive holes. Happy fitting. Cm Techniques for Better Fitting Four Steps to a Successful Wedge Fitting 1 Identify the appropriate specifications used in an iron fitting, including shaft flex, club length, grip size, lie angle, etc. Carry these measurements over to the wedges. 2 Select the necessary lofts to complement the wedge set. (Either three- or four-degree increments, depending on the golfer’s 14-club set configuration.) 3 Choose wedges with the bounce angles, sole design and width that meet the golfer’s versatility and performance needs. 4 Fit the wedges with shafts that will provide sufficient feedback on partial swings. Maintain a consistent length interval between each wedge and the next. Six Steps to a Successful Putter Fitting 1 Fit the putter for length using a gripless, uncut shaft. Determine where the golfer experiences the most control and comfort in his or her grip. 2 Set lie so that the sole is flush to the ground. 3 Identify loft by minimizing the skid of the ball. 4 Establish the static weight of the putter to provide enough mass to keep the wrists and elbows from being active in the stroke, so the golfer uses larger muscles, instead. 5 Fit the golfer into the largest diameter grip the golfer finds comfortable. 6 Ensure that face-balanced putters are fit only into the appropriate putting strokes.
